System and method to determine quality of termination of wire using thermal characteristics
A wire terminating system and method which allows for determining the quality of a wire termination. The method includes: terminating the terminal to the wire; monitoring the thermal data of the termination of the terminal to the wire with one or more thermal sensors; and comparing the monitored thermal data to stored thermal data to determine if the termination of the terminal to the wire is defective. The system includes a wire termination apparatus with a thermal sensor is positioned proximate a wire termination zone to acquire thermal data of the termination of the terminal to the wire. The thermal sensor monitors the thermal data of the termination of the terminal to the wire to determine if the termination of the terminal to the wire is defective.
